Hydrogen Hybrid Technologies Prepares For Car & Light Truck Aftermarket

Initial Field Trials Successfully Completed

PICKERING, ON, Aug. 28, 2008 - Hydrogen Hybrid Technologies Inc.(HYHY:otcbb) and Canadian Hydrogen Energy Company are pleased to announce that, in response to unprecedented demand and in line with its marketing plan, initial field trials have been successfully completed on a Hydrogen Fuel Injection (HFI) system specifically for the Car & Light Truck aftermarket.

With the increased concern about increasing fuel prices, consumers are anxious to find solutions. This particularly applies to Light Trucks, including SUVs. Plans are currently under way to extend the scope of these trials with specific emphasis on target customers.

HFI technology is installed as an add-on to diesel and gasoline engines where it significantly reduces a wide variety of emissions (CO, PM, HC, CO2 and NOx) while simultaneously reducing fuel consumption. Currently, HFI units are being used by long-haul transport trucks, ambulances, municipal buses and other heavy equipment, earning HFI the dominant position as the world's most widely-used on-board electrolysers. The technology is based on electrolysis and the units split water, on-board the ambulance, then vent the hydrogen and oxygen directly into the air intake of the engine. Adding hydrogen significantly improves the efficiency of combustion, in the engine, with significant financial and environmental benefits.

HFI is distributed through the world's largest retail distribution network for any hydrogen product, with over 140 Certified Installation Centres all across Canada, the United States, and a number of international markets. The product is the first emission control technology to have received "Environmental Technology Verification" (ETV) by the Canadian government and the first hydrogen technology to receive ETV recognition anywhere in the world.
